Summary:
Initial text provided to an SLComposeController of type SLServiceFacebook present in the compose controller only if the native Facebook app is *not* installed. If the app is present, the controller is empty.

Steps to Reproduce:
1. Remove Facebook app if it is present
2. Run attached sample app (*)
3. Press "compose"
4. Notice that the text "This is the text I want to post" is pre-populated in the share sheet
5. Kill the app
6. Install Facebook app. Sign in to Facebook via the app.
7. Run attached sample app again
8. Press "compose"

* - only interesting part of the sample app is this event-handler:
	@IBAction func handleComposeTapped(sender: AnyObject) {
		if SLComposeViewController.isAvailableForServiceType(SLServiceTypeFacebook) {
			let composer = SLComposeViewController(forServiceType: SLServiceTypeFacebook)
			composer.setInitialText("This is the text I want to post")
			presentViewController(composer, animated: true, completion: nil)
		} else {
			let alert = UIAlertController(title: "Can't post",
				message: "Composer not available",
				preferredStyle: .Alert)
			alert.addAction(UIAlertAction(title: "OK", style: .Cancel, handler: nil))
			presentViewController(alert, animated: true, completion: nil)
		}
	}


Expected Results:
The test "This is the text I want to post" should be in the share sheet, as before

Actual Results:
The share sheet is empty

Version:
iOS 8.4.1

Notes:
Apparently, this is a deliberate action by Facebook. See the discussion in a bug report here: https://developers.facebook.com/bugs/962985360399542/

Facebook's position is apparently that pre-populating a share sheet is against their developer polices, shown here: https://developers.facebook.com/docs/apps/review/prefill

But HOLY CRAP ON A CRACKER, since when does Facebook get veto power over iOS system APIs?!!

If they're really going to do this, it would be better for SLComposeViewController.isAvailableForServiceType(SLServiceTypeFacebook) to return false, because the share sheet is completely useless in this scenario.

Configuration:
iPhone 5s, 64 GB, AT&T
